李泳霖

1. int[] scores = { 50, 60, 70, 30, 20 };
   
2. System.Console.WriteLine(scores[0]);
   
3. System.Console.WriteLine(scores[1]);
   
4. System.Console.WriteLine(scores[2]);
   
5. System.Console.WriteLine(scores[3]);
   
6. System.Console.WriteLine(scores[4]);
   
7. scores[0] = 10;
   
8. System.Console.WriteLine(scores[0]);
   
9. 
   
10. //創建陣列當下不知道要存放甚麼?
    
11. //創建一個空陣列
    
12. string[] n = new string[3];
    
13. n[0] = "Leo";
    
14. n[1] = "Mary";
    
15. n[2] = "Kevin";
    
16. System.Console.WriteLine(n[0]);
    
17. System.Console.WriteLine(n[1]);
    
18. System.Console.WriteLine(n[2]);

假設五年級共有8個班: 1班有30人, 2班有31人, 3班有33人, 4班有32人, 5班有31人, 6班有35人, 7班有28人, 8班有29人. 試利用陣列與for迴圈, 列出五年級各班的人數.

1. int[] nums = { 30, 31, 33, 32, 31, 35, 28, 29 };
   
2. for (int i = 0; i < 8; i++)
   
3.     System.Console.WriteLine("5年"+(i+1)+"班有"+nums[i]+"人");
